  RE: MSP430FR59941: configure LFXO

  Thanks, Bruce: Believe it is working. You won't believe what I was doing. I was using another timer (also driven from ACLK). The other timer was timing out every .01 sec. So naturally no matter what the (common) clock source was, the time difference...

  RE: CCS/MSP430FR59941: Enabling of the SYSNMI interrupt

  Hi Connor, I don't think the code examples include this because the NMI source is internal, not external. Your customer's code looks right after reviewing the user's guide. My only comment would be to ensure SYSNMI is 0 in the SFRRPCR register...

  RE: CCS/MSP430FR59941: Compiler option to use 32-bit variables

  It turns out that the issue was related to how the variable was being displayed with printf. With previous GNU tools on linux system a %u or %d did not require a %lu or %ld to render a uint32_t as 32 bits. When ported using Code composer the printf with...

  RE: MSP430FR59941: Boundary scan and testing

  Correct: Device ID is in TLV table. In the section 6.14 of the device datasheet MSP430FR599x, MSP430FR596x Mixed-Signal Microcontrollers datasheet (Rev. C) , you can find the memory address for the device ID.

  MSP430FR59941: Can not enter BSL I2C mode when Vcc is 2.2 V

  Part Number: MSP430FR59941 Hi, In the MSP430FR59941 datasheet, it said MCU can run at 2.2V or 3.3V. But my customer set Vcc to 2.2V and it can not enter BSL mode to download program via I2C by external main chip. After testing, if VCC set to 2.9V...

  RE: MSP430FR59941: MSP430 JTAG support for boundary scan

  No. There is BYPASS command, but EXTEST and SAMPLE / PRELOAD is not supported. https://blog.asset-intertech.com/test_data_out/2016/09/boundary-scan-test-on-the-ti-msp430.html

  RE: CCS/MSP430FR59941: UART Interrupt not triggered on MSP430FR5994(1) when Code is flashed with CCS10

  Hi Dennis, your assumtion is correct. I worked around the temportary issue via copying the missing defines from the older driverlib file version. Good to read that the problem will be resolved in Q4. Best regards Lukas
